Antibiotics have been administered to agricultural animals for disease treatment, disease prevention, and growth promotion for over 50 years. The impact of such antibiotic use on the treatment of human diseases is hotly debated. This study examined differences in pigs receiving antibiotics and t... Read More
The bottom of a glacier is not the most hospitable place on Earth, but at least two types of bacteria happily live there, according to researchers.
The bacteria -- Chryseobacterium and Paenisporosarcina -- showed signs of respiration in ice made in the laboratory that was designed to simulate... Read More
Carnegie Mellon University researchers have discovered that an element commonly found in nature might provide a way to neutralize the potentially lethal effects of a compound known as Shiga toxin. New results published in the Jan. 20 issue of Science by Carnegie Mellon biologists Adam Linstedt a... Read More
Researchers from the University of Utah have identified a process by which the most common types of urinary tract infection-causing bacteria are able to trigger bladder cell shedding and disable immune responses. According to this new study, published in the Jan. 19, 2012, issue of Cell Host & M... Read More
Although there is an effective vaccine for hepatitis B and public health officials have a strong sense of who is at highest risk for the infectious liver disease, tens of thousands of people in the United States contract the virus every year. According to a new study by researchers at Brown Univ... Read More
The U.S. government’s request that the journals Science and Nature withhold scientific information related to the genetically modified H5N1 virus because of biosecurity concerns does not violate the First Amendment, say two Georgetown University professors.

A new study by engineering researchers at Rensselaer Polytechnic Institute demonstrates how introducing certain polymers—like those found in human mucus and saliva—into the environment makes it significantly more difficult for H. pylori and other microorganisms to coordinate.
“In the human bo... Read More
Fernan Federici, a researcher in the Haseloff Lab at Cambridge University and one of the Synthetic Aesthetics residents, studies how cells grow and develop into complex shapes and structures. Using confocal microscopy, he tracks the growth of plant cells and tissues, creating models of how cell ... Read More

The finding of viral nucleic acid sequences in illegally imported wildlife products has attracted the attention of the New York Times, which published an article entitled From the jungle to J.F.K., viruses cross borders in monkey meat. Read More
There was a lot of interest in in TDR-TB Friday; both the Leonard Lopate Show on WNYC and Science Friday kindly asked me to be on to talk about it.
While I was waiting for the phone link to Science Friday to become live, an alarming bulletin arrived in my email. The early-warning list ProME... Read More
PREVENTION is not always better than cure. The US Food and Drug Administration has finally moved to restrict the farmyard use of antibiotics to prevent livestock illness over concerns that they may generate antibiotic-resistant superbugs. But the announcement covers such a small subset of drugs ... Read More
